The current study investigated the extraction of orthographic and phonological structure of written words in adults with dyslexia. In adults without learning difficulties, Chetail and Content showed that orthographic structure, as determined by the number of vowel letter clusters, influences visual word length estimation. The authors also found a phonological effect determined by the number of syllables of words. In the present study, 22 French-speaking students diagnosed with dyslexia in childhood and 22 students without learning disabilities were compared. All participants performed the task of estimating word length. The pattern of results obtained by Chetail and Content was replicated: length estimates were biased by both the number of syllables and the number of vowel letter clusters. The study showed a significant interaction between phonological bias and group. The phonological effect was less important in students with dyslexia, suggesting reduced sensitivity to phonological parsing in reading. In contrast, the orthographic effect did not differ significantly between groups, suggesting that the sensitivity to the orthographic structure of written words is preserved in students with dyslexia despite their low-quality orthographic representations. We conclude that there is no systematic association between sensitivity to the structure of representations and quality of their content.

成人阅读障碍印刷词的拼写和语音结构提取

目前的研究调查了阅读障碍成人书面单词的正字法和语音结构的提取。在没有学习困难的成年人中，Chetail 和 Content 表明，由元音字母簇的数量决定的正字法结构会影响视觉词长估计。作者还发现了由单词的音节数量决定的语音效应。在本研究中，比较了 22 名在儿童时期被诊断为阅读障碍的法语学生和 22 名没有学习障碍的学生。所有参与者都完成了估计词长的任务。复制了 Chetail 和 Content 获得的结果模式：长度估计受到音节数量和元音字母簇数量的影响。该研究表明语音偏见和群体之间存在显着的相互作用。语音效应在阅读障碍的学生中不太重要，这表明阅读时对语音解析的敏感性降低。相比之下，组间的正字法效果没有显着差异，这表明阅读障碍学生对书面单词的正字法结构的敏感性保留了下来，尽管他们的正字法表示质量很低。我们得出结论，对表示结构的敏感性与其内容的质量之间没有系统的关联。这表明阅读障碍学生对书面单词的拼写结构的敏感性仍然存在，尽管他们的拼写表示质量很低。我们得出结论，对表示结构的敏感性与其内容的质量之间没有系统的关联。这表明阅读障碍学生对书面单词的拼写结构的敏感性仍然存在，尽管他们的拼写表示质量很低。我们得出结论，对表示结构的敏感性与其内容的质量之间没有系统的关联。
